NSA Involvement
"When warranted, the United States will respond to hostile acts in cyberspace as we would to
any other threat to our country
. All states possess an
inherent right to self-defense
, and we recognize that certain hostile acts conducted through cyberspace could compel actions under the commitments we have with our military treaty partners. We reserve the right to use
all necessary means
—diplomatic, informational, military, and economic—as appropriate and consistent with applicable international law, in order to defend our Nation, our allies, our partners, and our interests."

"It's the great irony of the Information Age – the very technologies that empower us to create and to build also empower those who would disrupt and destroy." - President Barack Obama
U.S. Department of Defense
• Invests over $3 billion into cyber defense annually
• Established U.S. Cyber Command
In order to help our nation's cybersecurity we must secure our own networks.

"Secretary Panetta's Speech About Cybersecurity." Oct 2012. Council on Foreign Relations. Dec 2013
Five strategic initiatives:
1. "Treat cyberspace as an operational domain to organize, train, and equip so that Department of Defense can take full advantage of cyberspace’s potential"
2. "Employ new defense operating concepts to protect DoD networks and systems"
3. "Partner with other U.S. government departments and agencies and the private sector to enable a whole-of-government cybersecurity strategy"
4. "Build robust relationships with U.S. allies and international partners to strengthen collective cybersecurity"
5. "Leverage the nation’s ingenuity through an exceptional cyber workforce and rapid technological innovation"
Spending too much money on offense

where its coming from
where its going
AFSA (Armed Forces Security Agency was established
AFSA redesignated as NSA (National Security Agency)
The Morris Worm -
First computer worm
Moonlight Maze - Computer probing discovered in networks at The Pentagon, NASA, and Department of Energy
USCYBERCOM (United States Cyber Command) was established

How do we put a monetary value on loss of intellectual property, reputational damage, or loss of sensitive business information?
"Nine trillion dollars a day moves through the
internet. And SCADA systems (Supervisory Control and Data Acquisition systems) - almost all of which are connected to the Internet for ease of use - power the financial system" - Tony Shaffer, cyber defense expert at the Center for Advanced Defense Studies
A breach of a central system can compromise an entire financial system
Firms suffer losses of 1%-5% in the days after a cyber attack.
For something like the NY Stock Exchange, this translates to shareholder losses of between $50 million and $200 million.
Department of Homeland Security
Defense Industrial Base
DoD revised its rules of engagement in cyberspace to spell out the duty of the military
Collective Cyber Defense
Ban together to punish offending countries like China
Training and education
Stronger encryption
Better policies
More effective detection systems to recognize and stop cyberattacks quickly
What we need to look out for:
Attacks on critical infrastructures (industrial control systems that are managed by computer systems)
water supplies
electrical grid
transportation systems (ex: railroad track switches, draw bridges, etc)
financial systems
Cyberterrorism + Physical Terrorism
Ex: bombing a city AND shutting down electricity at hospitols
"Confidentiality of Information"
